特開2001−136823号(段落〔0041〕、〔0053〕−〔0055〕、図2,3,7)JP 2001-136823 (paragraphs [0041], [0053]-[0055], FIGS. 2, 3 and 7) 特開2004−34780号(段落〔0013〕、〔0017〕、〔0018〕、〔0023〕、図11,14)JP 2004-34780 (paragraphs [0013], [0017], [0018], [0023], FIGS. 11 and 14)

特許文献1に示されるものでは、エンジンボンネット及び運転座席が自走機体横向きの軸芯まわりで回動することから、エンジンの上方に作業障害物がない状態にエンジンを開放することができるようにすると、エンジンボンネットや運転座席などを閉じ状態から高所まで上昇させる必要が生じ、開閉操作が重くなりがちであった。   In what is shown in Patent Document 1, the engine bonnet and the driver's seat rotate around the axis of the self-propelled machine body so that the engine can be opened without any work obstacles above the engine. Then, the engine bonnet and the driver's seat need to be raised from a closed state to a high place, and the opening / closing operation tends to be heavy.

特許文献2に示される技術を採用すると、エンジンを開放した際、エンジンボンネット及び運転座席が自走機体から横外側に大きくはみ出た状態になっていた。   When the technique disclosed in Patent Document 2 is employed, when the engine is opened, the engine bonnet and the driver's seat are in a state that protrudes largely laterally outward from the self-propelled aircraft.

本発明の目的は、エンジンを上方に障害物がない状態に開放できるものでありながら、エンジンボンネット及び運転座席を楽に移動操作することができ、かつ、開き状態になったエンジンボンネット及び運転座席の自走機体外への突出量を抑制することができるコンバインを提供することにある。   An object of the present invention is to allow the engine bonnet and the driver's seat to be easily moved and operated while the engine can be opened upward without any obstacles. An object of the present invention is to provide a combine that can suppress the amount of protrusion outside the self-propelled aircraft.

本第1発明にあっては、エンジンボンネットの上方に位置した運転座席を備えたコンバインにおいて、
前記エンジンボンネット及び前記運転座席を、エンジンよりも自走機体後方側で、かつ、エンジンの自走機体横方向での機体外側端よりも自走機体内方側に配置した自走機体上下向きの運転部開放軸芯まわりに、エンジンボンネットがエンジンを覆った閉じ状態と、エンジンボンネット及び運転座席がエンジンよりも自走機体後方側に位置してエンジンを開放した開き状態とに回動切り換え自在に構成してある。
In the first invention, in the combine provided with the driver seat located above the engine bonnet,
The engine bonnet and the driver's seat are disposed on the rear side of the self-propelled aircraft from the engine and on the side of the self-propelled aircraft inward of the outer end of the aircraft in the lateral direction of the engine. Around the driver's open shaft, the engine bonnet covers the engine in a closed state, and the engine bonnet and the driver's seat are located on the rear side of the self-propelled aircraft from the engine so that the engine is opened. It is configured.

すなわち、エンジンボンネット及び運転座席が、エンジンよりも自走機体後方側で、かつ、エンジンの自走機体横方向での機体外側端よりも自走機体内方側に配置した自走機体上下向きの運転部開放軸芯まわりに回動し、エンジンよりも自走機体後方側に位置した開き状態になってエンジンを開放するものである。これにより、エンジンボンネット及び運転座席を閉じ状態での配置高さと同一又はほぼ同一の配置高さのままで移動させてエンジンを開放することができる。また、開き状態になったエンジンボンネット及び運転座席が極力エンジンの後方側に位置し、エンジンボンネット及び運転座席の自走機体から外側への突出量を極力小にしながらエンジンを開放することができる。   That is, the engine bonnet and the driver's seat are located on the rear side of the self-propelled aircraft with respect to the engine and on the side of the self-propelled aircraft with respect to the lateral side of the engine in the lateral direction of the self-propelled aircraft. It rotates about the driving unit opening axis and opens the engine in the open state located on the rear side of the self-propelled machine from the engine. As a result, the engine can be opened by moving the engine bonnet and the driver seat with the same or substantially the same arrangement height as that in the closed state. In addition, the engine bonnet and the driver's seat that are in the open state are positioned as far as possible on the rear side of the engine, and the engine can be opened while minimizing the amount of protrusion of the engine bonnet and the driver's seat from the self-propelled body to the outside.

従って、本第1発明によると、開き状態になったエンジンボンネット及び運転座席がエンジンよりも自走機体後方側に位置して、エンジンの上方にエンジンボンネットなどの障害物がなくて点検作業などが行いやすい状態にエンジンを開放することができるものでありながら、エンジンボンネット及び運転座席を閉じ状態での配置高さと同一又はほぼ同一の配置高さのままで移動させて楽に開き操作することができ、かつ、開き状態になったエンジンボンネット及び運転座席の自走機体外への突出量が少なくなってエンジンボンネットなどが作業の障害物になりにくく、点検作業などが行いやすくなる。   Therefore, according to the first invention, the opened engine bonnet and the driver's seat are located on the rear side of the self-propelled aircraft from the engine, and there are no obstacles such as the engine bonnet above the engine, so that the inspection work can be performed. While the engine can be opened in a state that is easy to perform, the engine bonnet and the driver's seat can be moved while maintaining the same or almost the same height as when the engine is closed. In addition, the amount of protrusion of the engine bonnet in the open state and the driver's seat to the outside of the self-propelled aircraft is reduced, and the engine bonnet or the like is less likely to be an obstacle to the work, and the inspection work and the like can be easily performed.

本第2発明にあっては、本第1発明の構成において、前記運転部開放軸芯に平行な軸芯まわりで自走機体フレームに揺動自在に連結された支持フレームを備えるとともに、前記エンジンボンネットの遊端側を前記支持フレームの遊端側に摺動自在に支持させてある。   According to the second aspect of the present invention, in the configuration of the first aspect of the present invention, the engine further includes a support frame that is swingably connected to a self-propelled machine body frame around an axis parallel to the operating unit opening axis. The free end side of the bonnet is slidably supported on the free end side of the support frame.

すなわち、エンジンボンネットが開閉回動されると、エンジンボンネットの遊端側が支持フレームと摺動し合いながら支持フレームに操作力を付与し、これによって、支持フレームがエンジンボンネットの荷重を支持しながらエンボンネットに付いて揺動して、エンジンボンネットを開閉回動させる。   That is, when the engine bonnet is opened and closed and rotated, the free end side of the engine bonnet slides on the support frame to apply an operating force to the support frame, whereby the support frame supports the engine bonnet while supporting the load. It swings on the bonnet and opens and closes the engine bonnet.

従って、本第2発明によると、エンジンボンネットの荷重が支持フレームによって支持される分、エンジンボンネットをスムーズにかつ軽く回動させ、エンジンボンネットの開閉操作を一層軽く行うことができる。   Therefore, according to the second aspect of the present invention, the engine bonnet can be smoothly and lightly rotated as much as the load of the engine bonnet is supported by the support frame, and the opening and closing operation of the engine bonnet can be performed more lightly.

本第3発明にあっては、本第1又は第2発明の構成において、前記運転座席の前方に位置した運転部床及び操縦塔、運転部床の横側方で運転部の内外を仕切る横側壁、運転座席の横側方に位置した操作盤を備え、
前記操縦塔、前記横側壁、前記操作盤、前記運転部床が、前記運転部開放軸芯まわりで前記エンジンボンネットと一体に自走機体フレームに対して回動自在に支持されている。
In the third aspect of the present invention, in the configuration of the first or second aspect of the present invention, the driving unit floor and the control tower located in front of the driver seat, and the side that partitions the inside and the outside of the driving unit on the lateral side of the driving unit floor. It has an operation panel located on the side of the side wall and the driver's seat,
The control tower, the lateral side wall, the operation panel, and the operation unit floor are rotatably supported with respect to the self-propelled body frame integrally with the engine bonnet around the operation unit opening axis.

すなわち、エンジンボンネットを開き状態に回動させてエンジンが開放されると、操縦塔、横側壁、操作盤、運転部床もエンジンボンネットと共に回動し、エンジン前方側での自走機体も開放される。
これにより、エンジンボンネット、運転座席、操縦塔、運転部床、横側壁、操作盤を一挙に移動させて、エンジン、及び、エンジン前方での自走機体を開放することができる。
That is, when the engine is opened by rotating the engine bonnet to the open state, the control tower, the side wall, the operation panel, and the operation unit floor are also rotated together with the engine bonnet, and the self-propelled aircraft in front of the engine is also opened. The
Accordingly, the engine and the self-propelled aircraft in front of the engine can be opened by moving the engine bonnet, the driver's seat, the control tower, the driver's floor, the side wall, and the operation panel all at once.

従って、本第3発明によると、エンジンボンネット、操縦塔、運転部床、横側壁、操作盤を一挙に移動させてエンジン、及びエンジン前方での自走機体を速やかに開放し、エンジンの点検などの作業の他に、エンジンから走行装置や刈取り前処理部への伝動系の点検などの作業も能率よく行うことができる。しかも、エンジン前方側を作業しやすい状態に開放するのに、エンジンボンネットや運転部床などを閉じ状態での配置高さと同一又はほぼ同一の配置高さのままで楽に移動させ、この面からも有利に点検作業を行うことができる。   Therefore, according to the third aspect of the invention, the engine bonnet, the control tower, the operation unit floor, the side wall, and the operation panel are moved all at once to quickly open the engine and the self-propelled aircraft in front of the engine. In addition to the above work, work such as inspection of the transmission system from the engine to the traveling device and the pre-cutting processing unit can be efficiently performed. Moreover, in order to open the front side of the engine so that it can be easily operated, the engine bonnet, the operation part floor, etc. can be moved easily while maintaining the same or almost the same height as that in the closed state. Inspection work can be advantageously performed.
